Im shooting heavy metal again as well, so Ill be out there with my M1A and the 870I'll take that under consideration. What ammo does it like? The ammo I have loaded is 27.0 grains of BLC2 with a Hornady 55 FMJBT.
But I'll probably blow the cobwebs out of the .308. If they let me I might just run tac-irons with it and the SLP.
